Hey mk60,

Since no one else has replied.....might as well throw in my two cents.  

Several weeks ago Steve Deckert said "I am pleased to announce that we have our own 300B tube now. It comes as a result of over a year of testing. It is my pick/favorite sound of my collection. All of the tubes I've been testing are great with the WE300B leading the way followed by the Cryotone, but the WE300B is super transparent and neutral, and the Cyrotone is bold and dynamic. Both are also pricey. I wanted something a bit more laid back with a more addictive midrange and  less expensive. These are my ear candy 300B tubes. They make you want to listen because they have just the right color."  

Steve favors the Western Electric due to its transparency and neutrality.  Interestingly, that's pretty much the way I described the difference between Western Electric 300Bs and Sophia Electric Classic 300Bs a year or so ago.  Both are fantastic tubes, but the WE's transparency very well may place it as the tube to beat among the high dollar 300B contenders.  That's the way I hear it, for what it's worth.
